Validation

BananaJS ships with built-in validation: use @Body, @Query, @Params, and @Headers with a schema and the framework validates the incoming data automatically.

Install

npm install zod

The validation library is a dependency of @banana-universe/bananajs — your app should list it for direct schema imports.

Plugin status

@banana-universe/plugin-zod is decommissioned and removed from this monorepo.

Use the validation decorators directly from @banana-universe/bananajs:

• Body
• Query
• Params
• Headers

OpenAPI

Request body documentation is generated from your schemas via zod-to-json-schema (and from explicit @ApiBody({ schema }) when provided).
